load_lat_psf_performance

gammapy.datasets.load_lat_psf_performance(performance_file)[source]

Loads Fermi-LAT TOTAL PSF performance data.

These points are extracted by hand from:

As such, a 10% error in the values should be assumed.

Parameters:

performance_file : str

Specify which PSF performance file to return.

  • P7REP_SOURCE_V15_68 P7REP_SOURCE_V15, 68% containment

  • P7SOURCEV6_68 P7SOURCEV6, 68% containment
  • P7SOURCEV6_95 P7SOURCEV6, 95% containment
Returns:

table : Table

Table of psf size (deg) for selected containment radius and IRF at energies (MeV).
